This communication describes a general synthetic route to bicyclic amino acid-carbohydrate-conjugates, which would be useful as conformationally restricted hydroxyethylamine (HEA) transition-state isosteres. The synthesis was achieved in 12 steps starting from D-glucose. The striking features of this system are the bicyclic rigid core displaying an α-amino acid side chain and hydroxyethylamine moiety
该通报描述了双环氨基酸-碳水化合物-缀合物的一般合成路线,该路线可用于构象限制 羟乙胺(HEA)过渡态等位基因。从12个步骤开始进行合成d葡萄糖。该系统的显着特征是显示α-氨基酸侧链和羟乙基胺部分的双环刚性核-两者对于受体相互作用可能潜在重要,导致各种生物医学反应,如文献所述。晶体结构研究表明该系统中广泛的分子间氢键相互作用,涉及主链酰胺和羟基。
